Write to a Redis set

In the example below, data is captured from the source table named invoice and is written to a Redis set. The connection is an optional parameter that must refer to the corresponding connection name defined in config.yaml. When the data_type parameter is specified for the job, it overrides the system-wide setting target_data_type defined in config.yaml.

When writing to sets the additional argument member must be provided, specifying the field that will be written to a set. In this case, the results will be a Redis set with key names based on the key expression (e.g. invoices:Germany, invoices:USA) and with and expiration of 100 seconds. If no expire parameter is given, the keys will never expire.

source:
  server_name: chinook
  schema: public
  table: invoice
output:
  - uses: redis.write
    with:
      connection: target
      data_type: set
      key:
        expression: concat(['invoices:', BillingCountry])
        language: jmespath
      args:
        member: InvoiceId
      expire: 100
